To all whom it may concern: r

Be it known that we, FREDERICK M; BALDe WIN and GALUsHA A. BURGESS-7 both citizens of the United States, the "former residing at Los Angeles, in the county of Los'Angeles, State of Californimand the: latter residing at' Long Beach, in the county of Los An'geles,State of california have invented a new and" useful Shaft and Sleeve lowing is a specification.

This invention relates toyautomobile sig naling devices and is more particularly a device employing a signaling member ar-' ranged for outward extension in the three customary positions employed in imparting signals by an extended hand.

It is an object of the invention to provide a signaling device employing as adisplay member a replica of the human hand supported upon lazytongs, simple and eflicient means "for manipulating the lazy tongs.

in the use of Q pivoted leverlmemb'ers for supporting the 'laz'ytongs and. sleeve and shaft means whereby the lever members may .7 be simultaneously or separately swung upon their pivots insuch a manner that the lazy imparted by the hand thereof.

. It is a further object of the invention to.

evident hereinafter.

"f j I As shown in Fig.1 of the drawing, the in? vention is] particularly adapted for use on;

an automobile indieated at' llfaiidis par- 60 ticularly suited for mounting on the} side wall 12 thereof and is so constructed that itmay be quickly attached without necessity of dismounting the signal other thanre movingytheoperating handles 14: and 15 66 thereof; 1 V

"As shown in-Figs. 2 to 6 inclusive,: a

mounting plate 17 is employed which has plate members, such as indicated at 18' secured thereto so as to {form' ajcasing for receiving the mechanism mounted j upon the plate 17. Near the leftward 'end'of the plate 173s shown in Figs. 2 and 6, "an up standing wall 20 is formed, this "wall being depressed as indicated at 21' to" form'fa' de' V pression orjpock'etj 22 and ends 24: of the" wall being turned inwardly to formstops against which levermembers 25 and 26 rest during various "positions of the; lazytongs 28 which are'pivoted at 29. and 30,to the lever members 2.5 and 26. The' leverf' arms 25 and 26 are provided with bosses 32*atf. their inner ends which have b vergearseg: ment's 33 formed thereon which en age bevel gear segments 3 and 35 mounted upon" shafts 36 and 37.j The 'leverarms 251 and. 26'are pivoted 011 post members 40 which; may be secured to the plate member-17 by screws 41, Fig. l; screws 42 being employed} for retaining the lever arm. 1

Itswill be noticed that thewall portion 2 1 I and the blocksAO are bored to receive'the shaft-s 36 and 37 so that ample bearin therefor is provided. Covering the recess" 22 is a cover plate 44 arranged for securement" by screws 45 and having; extended ,I'outwardly therefrom a" tubular member 47. This tubular member shown as extending liniaf horizontal planesubstantially parallel with that of the signal member 28 is. in aligm ment' with thejshafty36 andjhasthjerein a" thereon, and onthe outer "endof the sleeve 48, the operating lever'15. is placed. The

gages a gear 52 mounted on the shaft 37. The shaft 36 has the operating lever 14 secured on the end thereof which extends from the sleeve 48.

It will be noticed that the levers 14 and 15 are provided with grips 55 and 56 which extend in opposite directions. By moving both levers simultaneously, the shaft 36 and sleeve 48 are simultaneously rotated, the r0 tation being transferred through the gears 50 and 52 to the shaft 37; With this manipulation of the levers 14 and 15, the lever members 25 and 26 will be swung rightwardly from the position in which they are shown in Fig. 3 to the position shown in Fig. 2, thus causing the extension of the lazy tongs in a horizontal direction, as indicated in Fig. 1. 7

If it is desired to extend the lazy tongs in a diagonally upward position, the grip 55 is manually engaged and the lever 14 swung from its normal position of rest, thereupon causing rotation of the shaft 36 and the upward swing of the lever member 26 into the position indicated by the dotted lines 60, Fig. 2, with the result that the lazy tongs are extended in the position indicated by the dotted lines 61.

If it is desired to extend the signal diagonally downwardly, the lever 15 is moved by engagement of the grip 56, thus transferring rotation through the sleeve 48, the gears 50 and 52, and the shaft 37 to the lever member 25, causing it to swing downwardly to the position indicated by the dotted lines 63, Fig. 2, with the result that the lazy tongs are extended as shown by the dotted lines 64.

The inner ends 65 and 66 of the shafts 36 and 37 extend through friction members and have secured on the ends thereon, torsion members in the form of springs 68 which exert rotational forces on the shafts in directions tending to maintain'the lever members 25 and 26 in retracted positions against the stops 24, as shown in Fig. 3. The friction members 67 as best shown in Figs. 4 and 5 are comprised of frames 70, mounted on the plate 17 by screws 71 and having therein cooperating friction blocks 73 and 74 which are semi-circularly channeled in their abutment faces to receive the shafts 36 and 37. The blocks 73 preferably rest in the ends of the frames as shown, whereas the blocks 74 are forced against the shafts 36 and 37 by spring -members 77 compressed by adjustment nuts 78 mounted on screws 79. By varying the compression of the springs 77, it is possible to vary the frictional engagement of the friction blocks 73 and 74 with the shafts.

The particular advantage and novelty of these friction blocks consist of means tending to resist rotation of the shafts 36 and 37, therefore tending to maintain the lazy tongs in any position to which they may be set. For example, it is desirous that the signal arm shall remain extended in a fixed position until retracted. This is accomplished by the action of the friction blocks which resist rotation of the shaft and thus prevent movement of the lazy tongs from the position to which they are extended by manipulation of the levers 14 and 15.

Another very pronounced advantage in the novel construction is found in the ease with which the device may be secured to an automobile. necessary merely to bore a hole 80, Fig. 3, through a wall 12 of the automobile at the desired point; removing the levers 14 and 15 from the shaft 36 and the sleeve 48; ex-

For securement thereof, itis tending the tubular member 47 through the hole 80; and screwing upon the inwardly extending end thereof a nut 81 which may be screwed forcibly against a washer 82 so as to tightly grip the wall 12. The levers 14 and 15 are then replaced and the signal is ready for use.

It will be plainly evident that the cheap-- ness of construction and reduction of the number of parts employed in the signal by use of the tubular member is particularly advantageous especially from a point of economical manufacture. The ease and installation is also of importance and the arrangement of parts in such a manner that tion of: a supporting structure; a signal member comprising lazy tongs having a display member at the end thereof; a pair of lever members pivoted on said supporting structure, said lever members being joined to the inner end of said lazytongs and arranged to operate said lazy tongs; a tubular member extending from said supporting structure; a sleeve. extending through said tubular member; a shaft disposed in said sleeve; means for rotating said sleeve and said shaft; means operatively connected be-v tween said sleeve and one of said lever mem: bers for swinging said lever member; and means operatively connected between said shaft and the other of said lever members for swinging said other l'ever member. 3. In an automobile signal,,the combination of: a supporting structure; a signal member comprising lazy tongs having a display member at the end thereof; a pair of lever members pivoted on said supporting structure, said lever members being joined to the inner end of said lazy tongs and arranged to operate said lazy tongs; a tubular member extending from said supporting structure; a sleeve extending through said tubular member; a shaft disposed in said sleeve; means for rotating said sleeve and said shaft; means operatively connected between said sleeve and one of said lever memhere for swinging said lever member; means operatively connected between said shaft and the other of said lever members for swinging said other lever member; and friction means mounted on said structure and arranged to resist the movement of said lazy tongs. y

In testimony whereof, we have hereunto set our hands at Los Angeles, California, this 11th day of August, 1923'.
